Glossary Term 5' (5-prime)
Definition A term that identifies one end of a single-stranded nucleic acid molecule. The 5' end is that end of the molecule which terminates in a 5' phosphate group. The 5' direction is the direction toward the 5' end. Nucleic acid sequences are written with the 5' end to the left and the 3' end to the right, in reference to the direction of DNA synthesis during replication (from 5' to 3'), RNA synthesis during transcription (from 5' to 3'), and the reading of mRNA sequence (from 5' to 3') during translation. See the Figure at NHGRI.
